Spermatogenesis and Oogenesis Differ in That

Spermatogenesis and oogenesis differ in that

A) spermatogenesis produces gametes with greater stores of raw materials than those produced by oogenesis.
B) spermatocytes remain in prophase of the first meiotic division longer than oocytes.
C) oogenesis produces four equally functional haploid cells per meiotic event and spermatogenesis does not.
D) spermatogenesis produces many gametes with meager energy reserves, whereas oogenesis produces relatively few, well-provisioned gametes.
E) spermatogenesis begins before birth in humans, whereas oogenesis does not start until the onset of puberty.
